Retractable Power Drive Surfboard for Wave Foils

ABSTRACT

This new art offers six add on motorized attachments for the benefit of the recent trend of hydro foil surfing wherein said wave hydro foils comprise a mast attached to the bottom side of a surfboard and a fuselage that has a large forward lifting wing and a small aft stabilizing wing and is able to lift a 250 lb man and surfboard approximately two feet above the water surface at slow paddling speeds riding a wave from underneath the water surface wherein said new art enables said hydrofoil surfboard to motor along on flat water at high speeds cruising or fielding for waves then said new art can retract a motorized structure completely out of the water while in motion to allow a surfer to catch then foil ride a wave or an ocean swell without power by means of two types of retractable motorized apparatus wherein the first type has a vertical strut that holds a propeller and cort nozzle in a down position motoring forward wherein said strut can retract horizontally up and out from the water surface wherein this retractable strut type can embody three similar versions. Also the second type has a torpedo shaped fuselage that contains a motor, a propeller and cort nozzle also embodying three similar versions that can travel up the foil mast stopping at said surfboard&#39;s bottom surface with the power shut off allowing the remaining under water foil apparatus to glide and free ride a wave or swell as it was designed to.

CROSS REFERENCE TO RELATED APPLICATION

It should be noted that all the control mechanisms for these six new retractable motorized foil surfboards will be taken from Derrah's Drive-N-Glide Surfboard Patents U.S. Ser. No. 13/489,367 and U.S. Ser. No. 13/677,133 as they will work perfectly for these new motorized water toys.

FIELD OF THE INVENTION

The present invention relates to personal watercraft; specifically, an electrically powered hydrofoil surfboard that is steered by weight shifts and able to retract its power structure to free surf without it.

BACKGROUND OF THE INVENTION

This application includes a reinforced surfboard that has its bottom surface connected to a wave riding foil that comprises a single mast that is approximately 7″ wide and can range between 2 and 3 feet long and has an equal side toil shape, wherein the top has a mast head that inserts into the surfboard's bottom cavity. The bottom of the mast is connected to a fuselage that is approximately 27″ long by 2″ square tapering to 1″ at the tail end. The front of the fuselage is connected to a large delta shaped front foil that is approximately 34″ long by about 12″ wide and is foil shaped with a maximum thickness of 2.5″ down to 0.1″. The smaller aft foil is attached at the opposite end of the fuselage and can be presented in different shapes and sizes but still be effective in stabilizing the front foil's lift to drag balancing act that takes place at anywhere between 3″ and 33″ below the ocean's surface.

The front foil has a convex upper surface with a concave bottom surface wherein the aft foil has tire opposite . . . a concave upper surface and a convex bottom surface. This is basically an airplane under water which in turn could be seen as D. Bernoulli's 18^(th) Century Principle of Foils lifting objects heavier than air or water that all airplane wings are based on, wherein no doubt D. Bernoulli's Principle is at work on these new surfboard to surf foil designs with a caveat . . . wave propulsion was not considered in the Swiss scientist's proforma. However, an airplane's forward thrust is provided by an engine and propeller, a kite foil's forward thrust is provided by the wind. A wave foil's forward thrust is provided by the various energies present in all ocean or lake waves; and require different designs. All waves have a forward moving, circular rolling inner-wave energy pulse. On large ocean swells wave foils travel along diving and lifting in the thick water stream moving up the wave's face and give the rider a long downslope ride. Whereas on a small wave the same foil can glide along effortlessly on top of the energy pulse itself.

The aft foil or “tail stabilizer” has a smaller size and an opposite convex to concave shape from the front foil wherein it flips the lift to drag equation to opposite as the water flows through them. This allows rider control to reach new heights! Even enabling top riders to self-propel themselves by pumping it like a skateboard on flat water without any motor or wave. The aft foil stabilizer is crucial in allowing this forward to backward self-propelling movement by skateboard enthusiasts on flat water. The thickness of the front foil particularly at the fore front of the leading edge gives the wave foil the ability to lift at slow speeds as outlined in Aguera U.S. Pat. No. 9,789,935B1.

This new wave foil's unique structure and special shapes that have the designed intent to gain forward movement in a water environment is un-precedented! This combination can lift a 250 lb. man and his surfboard two feel above the surface of the water and glide with very little resistance at high speeds on large un-broken wave swells or on waves as small as 1 foot traveling 3 times as fast as a regular surfboard could go, as well as enabling a smooth ride even in choppy surface conditions.

Hydrofoils have been used on surfboards ( U.S. Pat. No. 5,062,378 A. Bateman; U.S. Pat. No. 3,747,138 Morgan; U.S. Pat. No. 7,144,285 B1 Tarcah)

The modern wave foil can also be motorized. This is great for flat water foiling along at high speeds smoothly passing through choppy surface conditions without pounding, and moving forward in a marine environment with little resistance allowing battery life to triple compared to a motorized surfboard.

The drawback of the motorized foil is that when the large propeller and cort nozzle are not under power the motorized foil can't glide, ride waves or be pumped like a skateboard on flat water . . . so the need for a wave foiled surfboard that can do both is surmised.

SUMMARY OF THE INVENTION

Embodiments of the present invention improve upon the powered hydrofoil surfboard because it offers dual functionality, longer ran times and requires balance skills to operate especially when riding waves wherein making it more exhilarating, more interesting and more fun than just flat water cruising which is mostly all that single use powered hydrofoil surfboards do.

Embodiments of the present invention improve upon the non-powered hydro foil surfboard by reducing the effort required in paddling and by allowing long destination transportation to outside reefs or to motor out to a passing ferry boat to hitch a ride on its wake, retract the power means, then free foil the boat wake from land mass to land mass.

The intent of the present invention is to offer the best of both worlds so to speak, being able to motor around on flat water at high speed making weight shifts only to execute turns using the same method of control that is central to the experience of surfing, snowboarding and skateboarding, then to be able one up that by putting away the power structure while in motion to free foil a wake or swell under the wave's power only without having to have worked your but off to catch it makes this drive then glide concept a surfer's ultimate dream ride.

Agoera vs Derrah

Aguera's U.S. Pat No. 9,789,935 B1 outlines a three part apparatus that lifts a paddleboard and rider above the wave's surface as a rider maintains a slow speed in the water via paddeling. Furthermore, claims by Aguera concerning maximum thickness at first distance from the fore edge is the key to lifting a 250 lb man at slow paddling speeds on a heavy paddleboard whereas in 2018 the best surfers in Hawaii are catching waves by prone paddling small boards without a paddle, by standing up as the foil lifts and catches a wave. As difficult as this is to do many young surfers are agile enough to master this skill. Aguera's design appears to be most responsible for making foils that lift at slow speed and with a heavy rider which bodes well for beginners learning to foil.

Derrah has developed a drive-n-glide wave foil that has the advantage of dual functionality. It can motor around on flat water offering smooth rides with long run times. It can effortlessly catch a wave or swell under power and with the push of a button convert to a free gliding wave foil that can ride a swell for miles without power. None of the motorized surfboards or wave foils on the market are capable of catching and riding waves without power whereas Derrah's drive-n-glide design can ride on a wave's power done, gliding quietly with little resistance and using zero battery power.

Aguera's hydrofoil based apparatus revolutionizes wave riding but provides no way to add motorized propulsion to his watercraft whereas Derrah's add on invention does, making Derrah's six motorized versions of a drive-n-glide wave foil with surfboard different than Aguera's hydro foil based apparatus.

Langelaan vs Derrah

Langelaan's US 2017/028315 A1 discloses a personal hydrofoil watercraft that has a mast 103, a front foil 102, and a fuselage 201 with motor 105 and propeller and cort nozzle 104 but with no tail stabilizer. He outlines a version with a jet tube 401 placed underneath a front foil 102 with no tail stabilizer then shows a way to disconnect said front foil 102 from the fuselage 201 to use alternate shape and size front foils 102 and with the option of attaching two different tail stabilizers 804, 805 wherein it is not clear how they attach with any of the three power means outlined.

Langelaan's personal hydrofoil board reveals many design flaw's wherein the mast attached to the front wing or fuselage is very short and the absence of a tail stabilizer would make this apparatus very difficult to ride. This personal hydrofoil apparatus works only with the power on and the power means outlined would thwart any possibility of gliding and lifting without power wherein a fuselage, motor, propeller and cort nozzle cause water flow obstruction preventing the wave foil's ability to lift at slow speeds.

Derrah's six different versions of a drive-n-glide wave foil offer the advantage of dual functionality wherein three versions of Derrah's present invention have a vertical strut that holds a propeller and cort nozzle that completely retracts up and out of the water and wherein three other versions have a fuselage that contains a motor, propeller and cort nozzle that travel up the foil mast to touch the surfboard bottom, up and out of the water. All versions retracting any obstructions to water flow enabling the foil to do its job without power.

Langelaan's powered hydrofoil board provides no means to disengage the obstructions to water flow whereas Derrah's six versions of a drive-n*glide wave foil provide the means to retract all obstructions to water flow.

Trewern vs Derrah

Trewern's patent application WOZA19/104378 A1 discloses a hydro foil system comprising a fuselage 10 a motor 11 a propeller and a cort nozzle 13 connected to a front wing 14 and having a tail wing and allowing for a mast that connects to a surfboard. This design is known worldwide as the Fliteboard. This is a sound design for a single use (flat water cruising) motorized foil board. However, it cannot ride a wave without the power on. With the power on it is restricted from full wave riding performance because the propeller, cort nozzle and fuselage all contribute to create drag and disturbance of water flow.

Trewern's powered hydrofoil system is a sound design hydrofoil for powered flat water cruising but provides no means to retract the extraneous obstructions to water flow ie. fuselage, motor, propeller and cort nozzle in order to lift and glide on a wave like Derrah's drive-n-glide motorized wave foil does. The fact that all six versions of Derrah's drive-n-glide wave foil incorporate a means to retract obstructions wherein their intent is to use any top quality wave foil currently manufactured such as GoFoil, Naish, ect. to perform the lifting, gliding and free surfing demonstrates the difference between Trewern's foil system and Derrah's dual functionality foil designs.
